Subject: FW: Diesel Vanagon Conversion
Content-Type: text/plain; charset="iso-8859-1"
Hi everyone,
The e-mail below is from Tom Carrington. I had e-mailed him regarding a
1982 diesel Westy that had a 1986 1.8 Jetta engine installed in it. Not
being familiar with these conversions (my previous buses were all early '70s
type II's), I had a few questions about the car. Tom answered them very
well, but he also suggested that I send mail to this list to see if anyone
in the area (San Jose, CA) could help. Below is my original e-mail to Tom,
his response, and my response back to him.
Thanks in advance,
jeff

That's a good question. I think probably because he is kind of like a
middleman. He works for one of those car charities where people donate
their cars and they fix them up and resell them. This one was donated by
the original owner and the guy doesn't want to auction it off because he's
afraid some dealer or reseller might come in and lowball him, and he says
he'd like to get what the car is worth. In other words, it's not really his
car, so I don't think he wants to put any work into it.

I was thinking of that. I have a compression tester, but I didn't think to
bring it with me. The engine sounded pretty tight. It loped at first, but
once the cold start valve kicked the idle down, it hummed pretty smoothly.

I agree. He said it was due to the throttle cable, which has a weird angle
to it because the engine is mounted sideways. I'd say it has about a 230+
degree angle to it, which would definitely cause some drag. The pedal did
feel stiff, and in fact I stalled it a few times because I was not pressing
hard enough on the pedal.

Also a good idea; I've done that in the past. I'll bring it up and see what
he says.

I will do exactly that. Thanks for the tip

I will and thanks again!
